Isolates of Pseudomonas fluorescens (PT5) was examined for growth promotion and induced systemic resistance against Fusarium wilt of mungbean. Significant increase in germination percentage, root and shoot length and seed vigor index were observed in Pseudomonas treated plants. However, plant growth was inhibited when isolates of Pseudomonas were used in combination with Fusarium oxysporum f. sp. It was also observed that the Pseudomonas spp. was colonized in root of mungbean and significantly suppressed the disease in pot condition. Also showed greater disease control in the induced systemic resistance (ISR) that indicated maximum biochemical activity viz., Phenylalanine ammonia lyase, Peroxidase activity, Polyphenol oxidase activity, Lysyl oxidase activity and Chitinase activity in seeds treated with PT5. Biocontrol of plant diseases through induction of systemic resistance is an environment friendly substitute to chemicals in crop protection measures. Different biotic and abiotic elicitors can trigger the plant for induced resistance.
